  • a message that the first wind direction adjustment louver 13a is being set is displayed on the remote control 20.
  • a set command to set the open-close status of the first wind direction adjustment louver 13a is output from the remote control 20 to the control device 15.
  • a command to set the first wind direction adjustment louver 13a is acquired or an OK command is acquired. If a set command is acquired ("SET COMMAND IS ACQUIRED" in step SA5 in Fig. 12 ), the control device 15 moves the first wind direction adjustment louver 13a at the ceiling panel 11 in a direction (e.g., the second direction) as an open-close status in the acquired set command. The second to fourth wind direction adjustment louvers 13b to 13d at the ceiling panel 11 are left in a fully-closed state. As shown in Fig. 4 , a message that the first wind direction adjustment louver 13a is being set is displayed on the remote control 20 (step SA6 in Fig. 12 ).
  • the manipulator presses the OK button 54 in Fig. 4 on the remote control 20 after a command to set the open-close status of the wind direction adjustment louver 13, an OK command is output from the remote control 20 to the control device 15.
  • the manipulator can also press the OK button 54 in Fig. 4 without setting the open-close status of the wind direction adjustment louver 13 on the remote control 20 (i.e., without selecting the numeric button 51). In this case, a set command is not output from the remote control 20 to the control device 15, and an OK command is output.
  • step SA7 in Fig. 12 It is judged in the control device 15 whether an OK command is acquired after the acquisition of the set command. If an OK command is acquired (YES in step SA7 in Fig. 12 ), a position of the first wind direction adjustment louver 13a at the ceiling panel 11 is fixed. After the fixation, while the open-close status of the first wind direction adjustment louver 13a at the ceiling panel 11 is kept in the open-close status set by the set command, the piece of information of the new open-close status (the wind direction) of the first wind direction adjustment louver 13a is stored in the storage section 31 (step SA8 in Fig. 12 ). If an OK command is not acquired after the acquisition of the set command (NO in step SA7 in Fig. 12 ), the control device 15 waits for a command to set the wind direction adjustment louver 13 to be acquired, and the flow returns to step SA6 in Fig. 12 .
  • step SA5 in Fig. 12 If a command to set the first wind direction adjustment louver 13a is not acquired and an OK command is acquired in step SA5 in Fig. 12 ("OK COMMAND IS ACQUIRED" in step SA5 in Fig. 12 ), setting of the open-close status of the first wind direction adjustment louver 13a is regarded as being skipped, the piece of information of the open-close status of the first wind direction adjustment louver 13a stored in the storage section 31 is read out, the first wind direction adjustment louver 13a at the ceiling panel 11 is moved to a position indicated by the read-out open-close status, and the open-close status of the first wind direction adjustment louver 13a is kept at the position (step SA9 in Fig. 12 )
  • a message that the second wind direction adjustment louver 13b is being set is displayed on the remote control 20 (step SA10 in Fig. 13 ).
  • open-close status setting is performed for the wind direction adjustment louvers 13 subsequent to the second wind direction adjustment louver 13b (steps are not shown).
  • the open-close status of the fourth wind direction adjustment louver 13d is set to an open-close status from the remote control 20 or is set by reading out the open-close status stored in the storage section 31, setting of the open-close statuses of all of the first to fourth wind direction adjustment louvers 13a to 13d is complete, and all of the wind direction adjustment louvers 13a to 13d at the ceiling panel 11 are kept at respective set positions (see Fig. 9 ).
  • a screen for prompting checking as to whether details shown in the region 55 are satisfactory as settings for the wind direction adjustment louvers 13 is displayed on the remote control 20 (step SA11 in Fig. 13 ).
  • step SA12 in Fig. 13 It is judged whether "Yes” is pressed on the screen for prompting checking in Fig. 6(A) . If “No” is pressed (NO in step SA12 in Fig. 13 ), the flow returns to step SA4 in Fig. 12 to return to the setting of the first wind direction adjustment louver 13a. If "Yes” is pressed in Fig. 6(A) (YES in step SA12 in Fig. 13 ), it is judged whether the operation status of the air-conditioning apparatus 1 at the start of the wind-direction-per-louver setting is in-operation. If the operation status of the air-conditioning apparatus 1 is in-operation (YES in step SA13 in Fig.
  • step SA14 in Fig. 13 the operation of the air-conditioning apparatus 1 is resumed in a state before the operation stoppage (step SA14 in Fig. 13 ).
  • step SA14 in Fig. 13 all of the wind direction adjustment louvers 13a to 13d at the ceiling panel 11 are put into the set open-close statuses, and the operation is resumed while various settings other than the open-close statuses of the wind direction adjustment louvers 13 (e.g., the air volume and the operation mode) are unchanged from the state before the stoppage of the indoor unit 2.
  • the remote control 20 returns to the normal display, as shown in Fig. 6(B) (step SA15 in Fig. 13 ), and the process ends.
  • step SA13 in Fig. 13 If the operation status of the air-conditioning apparatus 1 at the start of the wind-direction-per-louver setting is not in-operation (NO in step SA13 in Fig. 13 ), all the wind direction adjustment louvers 13 at the ceiling panel 11 are put into a fully-closed state (see Fig. 11 ) after the set open-close statuses of all the wind direction adjustment louvers 13 are stored in the storage section 31, the remote control 20 is turned off (step SA16 in Fig. 13 ), and the process ends.
  • the control device 15 may be configured such that all or some of the above-described processes may be handled separately by software.
  • the control device 15 includes a CPU, a main storage device, such as a RAM, and a computer-readable recording medium having recorded thereon a program for implementing all or some of the above-described processes.
  • the CPU reads out the program recorded on the recording medium and executes information processing and computation processing, thereby implementing the same processes as the control device 15.
  • Examples of the computer-readable recording medium include a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, and a semiconductor memory.
  • the computer program may be distributed to a computer via a communication link, and the computer having received the distributed program may execute the program.
  • the open-close status of the next wind direction adjustment louver 13 is set in order while the open-close status of the wind direction adjustment louver 13 after completion of setting is kept.
  • the air-conditioning status of a region to be air-conditioned by the indoor unit 2 is obtained as an actual air-conditioning status.
  • the open-close status of the wind direction adjustment louver 13 can be adjusted while checking whether a desired air-conditioning status is achieved. It is possible for a remote control manipulator to easily know that adjustment of the open-close statuses of all the wind direction adjustment louvers 13 is complete by visually checking that a plurality of wind direction adjustment louvers 13 provided in the indoor unit 2 are all in an open state.
  • wind-direction-per-louver setting is performed after stoppage of the indoor unit 2 of the air-conditioning apparatus 1 if the indoor unit 2 is in operation
  • the present invention is not limited to this.
  • wind-direction-per-louver setting may be performed while operation of the indoor unit 2 is stopped.
